1. The service

Lockcheck.online provides a service that checks the status of a mobile phone based on the IMEI number and model you provide.

2. Check results

Check results are information to support your decisions only. They are not a certification of the device's status, and they may be incomplete or change later.
You should verify further before buying, selling or entering into any transaction involving the device.
If you enter an incorrect IMEI number or model, the check result will be incorrect.

3. User accounts

You are responsible for all use under your account. We may suspend or terminate accounts that violate these Terms.

4. Credits

Each check uses credits at the rate shown on the Check device page.
You can top up credits through an administrator as described on the Credits & refunds page, or receive credits by transfer from an authorized reseller we have appointed.
Credits transferred to you by an authorized reseller can be used in the same way as credits you top up yourself. Payment to a reseller is an arrangement between you and that reseller. If the credits you receive do not match what was agreed, contact the reseller or us.
If a check fails but credits were deducted, you may submit a credit refund request within 30 days from the date of the check. An administrator will review each request case by case.
Authorized resellers may transfer credits only to members, and only to the email address the member has provided. Searching for email addresses at random or by guessing is prohibited. A transfer made in error can be corrected only by an administrator, and we may revoke a reseller's authorized status if we find improper use.

5. Prohibited activities

Using the service for any unlawful or fraudulent act, or to infringe the rights of others
Using programs or automated means to send requests or extract data
Attempting to avoid credit deductions or to bypass the system's security measures
Copying, disassembling or reverse engineering our website or systems
Reselling check results or the service, or using them to provide services to others, without written permission

6. Intellectual property

The website, software, data and content of lockcheck.online belong to us. They may not be copied or used without permission.

7. Service availability

We may take the service offline for maintenance, limit usage, or stop providing parts of the service as necessary.

8. Limitation of liability

To the extent permitted by law, we are not liable for any damage arising from decisions made based on check results or from service disruptions. Our total liability will not exceed the value of the credits used for the transaction concerned.

9. Changes to these Terms

We may amend these Terms from time to time. If you continue to use the service after a change, you are deemed to accept the updated Terms.

10. Governing law

These Terms are governed by the laws of Thailand.
